You inspired me to go back and try to improve on a video I'd done using Wan 2.2, but using a fairly unrestricted version of Wan 2.7 this time. It came out much better now, although there are still details I'd like to improve. (Way too much wet, sloshing noise from the blood, for one thing.)

It only took, what? Maybe about 15 tries at tweaking then totally rewriting the prompt to get here?

Here's the prompt:

> STATIC SHOT. The camera angle is fixed and does not move, zoom, or cut for the entire 15-second duration. In a stark, bright tiled room, a brunette woman is shackled to the wall. A blonde woman stands to the viewer's left. The blonde holds a large kitchen knife against the brunette's right breast (the breast on the right side of the frame).
>
> While the brunette whimpers in fear, the blonde cheerfully purrs in a hushed whisper, in an Essex accent, "This is going to be fun."
>
> At second 3, the cutting begins, blade pressing close to the woman's rib cage so that as much of the mass of the breast is cut off as possible. The cutting action is extremely rapid, taking only 6 seconds. The blonde severs the breast with swift sawing motions, causing blood to flow, the blade advancing with each pass. At second 6, the brunette clenches her teeth and screams, eyes wide open in pain. At second 9, the severed breast falls out of view, leaving behind a flat, torn bloody wound. Nothing regrows, nothing regenerates.
>
> At second 10, the blonde cups the brunette's remaining breast (the breast on the left side of the frame) in her other hand (the hand not holding the knife), and while sensually fondling the breast, says "Now it's this titty's turn", and then gives the nipple of the breast a kiss while the brunette sobs in pain.

This was also I2V, not just T2V. Here's the starter image, a mix of stuff made with Qwen and assembled in Photoshop: https://files.catbox.moe/51w51z.png
